WEED-CUTTER.

SPEGIFICATION forming par t of Letters Patent N o. 514,312, datedFebruary 6, 1894.

Application filed J'ul 18. 1893. Serial N0. 480.807. (N0 model.)

Be it k1fiown that I, ROBERT HAYES Dona- State of Washington, haveinvented a new lowing is a fnll, elear, and exaet deseription.

My invention relates to an improvement in weed entters, and lt has forits objeet 130 provide a weed cntter in which the main cntters Will bepraetically of V-shape and so placed tl1at their innen eges Will betheir cutting edges, the angle of the cut.te' rs being at the rear.

A further object 0f the inventionis to pro- Vide in conjnnction with themain cutters upright entters, and also t0 provide a eonneetion betweenthe two sets of cntters, and a means whereby the entters may beeonveniently and expeditionsly adjusted to cover more 01 less ground, 01adaptthernselves to rows ofdifierent widths.

Another featnre 0f the invention eonsists in providing an adjustablehandle for the weed cutter, whereby it may be gnided conveniently bypersons 0f large ot of small statnre.

The inventioneonsists in the novel eonstrnetion and combination of theseveral parts, as will be hereinafter fully Set forth and ointe ont inthe claims.

Reference is to be had to the accornpanying draizvingsforming a pa.rt of.this speeifieation, in'which similar figures 0f reference indieatecorresponding partsin all the views.

Figure 1 is a plan view of the weed eutter. Fig. 2 is a side elevationthereof; and Fig. 3

the line 33 of Fig. 2.

The body of the maehine eonsists 0f a frame, whitsh fram6 comprises twosegmental freut bars 10 and 11, whieh bars overlap, and are adapted toslide one upon the'other, the two bars at their outer ends beingprovided with registering longitudinal slots 12; and in addition to thefront bars 10 and 11, the frame consists 0f two rear bars 13 and. 14,whieh bars at their inner ends are provided. with eyes, and at theirouter ends have adisk like formation, or eircnlar extensions 155 in theright-hand bar 13, for example, a recess 16 is formed over its circularextension 15, while a similar recess is formed upon the under faee ofthe extension of the opposite bar. Thus the forward extremities of theback bars are of less thickness than their other portions, and therecessed snrface 0f one bar is nppermost, while Ihat of the opposite batfaces downward.

The reeessed surfaees of the rear bars 13 and 14, are adaptedforengagement with the rear extrernities ot the front segmental ba'rs 10and 11, the right-hand bat l3being made to rnn upon the righ t-hand bar10, while the left-hand front bar 11 rests upon the corresponding rearbar 14. The front and rear bars are pivotally connected throngh themedin1n of threaded pins or bolts 17, provided with sitable lock nuts18, and the said plus or bolts are firmly secured to er made integralwith vertical cntters 19. The eutters are inelined in direction of 1hefrontof the machine, and are provided with an enlarged preferablycircnlar head 20, in Whiel1 the bolts 01 pins are secnred, the headsbeing adapted forengagement with the nnder sides of the frame, theleft-hand entter bar engaging with the left-hancl rear bar o'f thefrarne, while the right-hand cntter barat its head will engage with theright-hand forward bar of the fran1e. The eutters are preferablyflattened upon their side faces, as shownin Fig. 2, and t-l1eir lowerends are more 0r less beveled.

Adraft bearn 21is provided in connection With the frame, aiid is adaptedto extend fronn freut to rean'of the frame across the central portionthereof- In the forward'portion 0f the dratt bearn 21 a slot or opening22, is produeed, throngh whieh the overlapping ends of the front bars 10and 11 of the franne are passed, while at the rear end of thedraftbeaman aperture is produeed, and the innen ends of the two rear bars 13and 14 are canried one upon the othe1, and both of them fill theapertured portion of the draft bearn, and the draft beam and the tworear bars are conneeted by a third npright entter 19, of similareonstruetion to the forward entters, the threaded pin or screw whereofispassed through the apertnre 01: thebearn and throngh the eyes of thesaid rear bars 0f the fran1e, as is best shown in Fig. 2.

A bracket 23, is seeured upon the draft beam between the front and. rearof the frame, which braeket is provided ab its rear portion withupwardly and forwardly eurved conoenurio rnembers 23. These members areprovidecl With longitndihal ourved slots 24, asis also shown in Fig. 2,anc'l the braoket is further provided near the forward portion of theframe with parallel npright members 23". The lower or forward end of ahandle 25, is pivoted between the forward members 23", and the saidhandle is passed rearward through the eurved members 23 of the bracket,and the handle may be given more or less of an inclination in Order thatthe machine may be guided hy aperson of large er of small stature, bypassing a Set serew 26 through the handle and through the slots 24 ofthe brackei.

A caster wheel 27, is located at the frontof the maohine, ii; beingjournaled in a pedestal 28, which pedestal is adjustably conneetecl withthe (lraft beam immediately in front of the forward end. of the frame,asis likewise best shown in Fig. 2, the adjustment being efieoted byproducing slots 29 in the pedestal and passing a set sorew 30 throughthe slots and throngh the beam.

It will be observed that the vertieal or standing cutters aretriangularly arranged, and that the distanee between the forward euttersmay be inoreased or deereased by simply loosening the nuts upon thescrews 17 of the cutters and sliding the front bars inward, or oarryingthe1n outwarcl as may be desired, and when a properadjustmentisobtained, the frame is rigidly held in the desired position by cheadjusting or set screw 31, whieh is passed through the beam ancl throughthe slots 12 in the front bars.

In addition to the upright cutters 19, h0li zontal cutters 32, areexnployed. These entters consist preferably of thin metal blades,arranged at right angles to eaeh other, or substantially in theform of aletter V, their inner edges 33, being eutting edges, and said edges arepreferably beveled at the top, as is best shown in Fig. 3. Thehorizontal blades or onters are adapted to follow the adjustment oftheframe and the vertical orupright outters, and 110 that end the front;upright or vertical eutters are pivotally oonneeted with the forwardends of the horizontal blades, while the rear vertical or nprighteutteris pivotally oonnected with the overlapping ends of both of thehorizontalblades. Therefore, instead of the angle of the V-horizontalcutters being in direetion 0f the front in is in the direction of therear,and the Ventters, as the maohine advanoes, present their inneredges to the weeds.

It is evident that in adjusting the frame the V-outters will followsairladj ustrnenb, and that therefore they n1ay travel over a greater or lessexpanse of ground, and may be readily adj usted 110 any widtsh of row.

The maohine is exoeedingly simple, it is durable and it is economic,and. its adjustment may be expedit ionsly and eonveniently elfeeted.

I-Iaving thus deseribed my invention, I claim as new and desire tosecure by Letters Patent- 1. In a weed eutter, the eombination, with anadjust-able fraxne, and uprights adj ustable with the fraxne, 0fhorizontal cntters comprisr ing blades pivotecl ab one end am]. arrangedin substantially Vhape, the uprights of the frame being pivotallyconneeted with the eonneeted end of the blades at their outer ends, theeonnection between the horizontal blades ancl the nprights beingindependently eifeot ab the jnnetion of the rear bars with eaoh other,and horizontal outters arranged in the shape of a V, the forward uprightcuttersbeing pivotally eonneotedwith the diverging ends of thehorizontal blades or outters, and a rear upright eutter being pivotallycounected with the overlapping ends of the said horizontal bladesoreutters, as andfor the purpose speeified.

3. In a weed outter, theoombination, With a frame oomprising a Grafitbar, frontbars of segmental form, theinner ende of whieh overlap andhave sliding and adjustable connection with the draft beam, and -rearbars pivotally connected with the rear ends of the segmental front barsand with .therear extrernity ofthe draft beam, of uprighteutterspivotally eonneeted with the frame at the jnnction of the rear and frontbars anti the junetion of the rear. bars with thebeam, horizontalontters havingone of their ends overlapping and theopposite endsdiverging from each other, the upright eutters being pivotally conneetedwith the horizontal eutters, an adjustable oaster wheel located upon thebeam in front of the frame, andan: adjustable handle oonneotedwiththebeam, asan(l for thepurpose speeified.
